Reporter: Andy Grove
I am running automated benchmarks in k8s, using spark-submit in cluster mode, so the driver runs in a pod.
When running with Spark 3.0.1 and 3.1.1 everything works as expected and I see the Spark context being shut down after the job completes.
However, when running with Spark 3.0.2 I do not see the context get shut down and the driver pod is stuck in the Running state indefinitely.
This is the output I see after job completion with 3.0.1 and 3.1.1 and this output does not appear with 3.0.2. With 3.0.2 there is no output at all after the job completes.
